Damn, this works like a charm! I was looking for something like this since I migrated to WP3.0, thanks!

I had that yesterday as well. For me it helped to untick “Update siteurl and home as well.”

Ah, it appears that you have completely disabled http (80). Instead, you could allow http to reach certain redirects in Apache, like this:

<VirtualHost <IP Adress>:80>
    ServerName domain.com
    Redirect 301 / https://domain.com
</VirtualHost>

Hi sjcundy,

A simple “define(‘FORCE_SSL_ADMIN’, true);” in your wp-config.php could also do the trick, but in my case it caused certificate errors, so I use apache’s mod_rewrite to get it done. More info can be found here: Admin over SSL

For multisite, you can use the %{SERVER_NAME} variable, so the subdomains in the url stay the same.

Only prereq is that mod_rewrite is active in apache.
Here’s my setup:

# https://domain.com
<VirtualHost <IP-Address>:443>
        # I'll skip the standard stuff for SSL.
        <IfModule mod_rewrite.c>
                # If no https is needed, revert back to http.
                # I specifically added includes and content, because I ran into some issues with plugins.
                RewriteEngine On
                RewriteRule !^/wp-(admin|login|signup|includes|content)(.*) - [C]
                RewriteRule ^/(.*) http://%{SERVER_NAME}/$1 [QSA,L]
        </IfModule>
</VirtualHost>

# http://domain.com
<VirtualHost <IP-address>:80>
        # I'll skip the standard stuff again. Add the following rewrite lines to your Directory
        <Directory>
                <IfModule mod_rewrite.c>
                        RewriteEngine On
                        RewriteBase /
                        # If the url leads to wp-admin/login or signup, switch to https
                        RewriteCond %{REQUEST_FILENAME} -f [OR]
                        RewriteCond %{REQUEST_FILENAME} -d
                        RewriteRule ^wp-(admin|login|signup)(.*) https://%{SERVER_NAME}/wp-$1$2 [C]
                        RewriteRule ^.*$ - [S=40]
			# WP rules from .htaccess file, I like to keep them in one file.
			RewriteRule ^index\.php$ - [L]
			# uploaded files
			RewriteRule ^files/(.+) wp-includes/ms-files.php?file=$1 [L]
			RewriteCond %{REQUEST_FILENAME} -f [OR]
			RewriteCond %{REQUEST_FILENAME} -d
			RewriteRule ^ - [L]
			RewriteRule . index.php [L]
                </IfModule>
        </Directory>
</VirtualHost>

ps. I adjusted the above today for multisite, as I migrated myself only this week. Some brief tests showed that it works for all my subdomains. For example: I go to http://blog1.domain.com/wp-login, and it redirects me to https://blog1.domain.com/wp-login.

Is this what you were looking for?
